forms – Save the field on tap (Textarea, text entry) – what is the best approach

I am building an application where I have a shopping list that has a name and description.

The name field is an input field, the type of text and the description is textarea.

Currently, we manage to update Name and Description if the user presses the Enter key or the Esc key, but for me it is a little confusing.
Update entry field on Enter, press for me, it's good. But textarea, where the user wants to create a multiline message with line breaks, is not intuitive and confusing and must be done with the "Save" button.

What is your opinion??
